Application 'filed October 4, 1907. Serial No. 395,817.

To all whom it may concern:

Be it known that I, ARNOLD E. DE FRANCE, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Switch-Mountings; and I do hereby declare that the following is a full, clear, and exact description'thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being'had to the accompanying drawings, and to the figures of reference'marked thereon, which form part of this specification.

This invention has reference to improved means for mounting snap swltches, and the same embodies the novel -C0l11b1I1SttlOI1, ar-

rangement and details of construction hereinafter shown, described and claimed.

In the accompanying drawings, illustrative of a preferred embodiment of the invention, Figure 1 is a plan view of the switch mounting as it a pears when plastered in u on a' wall in rea( iness to receive a snap switc ,.the

-wire terminals and the flexible covering therefor being shown in position; Fig. 2 is a cross section of the same online xae in Fig.

1, the switch being shown partly in elevation; Fig. 3 is a plan view of the mountin in position before the wall is lathed and p as tered; and Fig. 4 is a plan view of the bottom late of the mounting showing the means for fastening the flexible covering for the wire terminals.

Iteferring to the details, 1 is a bottom plate of substantially rectangular outline and the same is provided with a lurality of perforations 3, 3, 3, 3 through wliich the flexible covering or. tubing 4 for the wire terminals are directed,and the margins 5 of the .perfo rations are deflected from the plane of the plate 1 to provide a plurality of engaging tongues 6 around'each perforation adapted to'firmly embrace the flexible covering and hold the 'same from being withdrawn after insertion through the perforations. Mounted upon the bottom plate and extending outwardly therefrom is a sheet metal boxlike inclosure 7 of substantially cylindrical form and 0 on at the front and rear, the top margin 8 o the sides serving as a su port for the switch 9, and extending inwardlyat onposite points from the top margin 8 of t e inclosure are integral lugs 10 having threaded perforations 11 to be engaged by ordinary screws l2'passing through the base of the switch and securing the same in place.

The box-like inclosure 7 is also provided with integral lugs 13 extending outwardly from its lower margin, the'ends of the lugs fitting within the upturned margins 13" of the corners of the bottom plate, and both the bottom plate and the lugs 13 are provided with registering perforations through which screws 14 are directed to secure the bottom plate and the inclosure 7' in assembled relation upon a wall.

The complete device isshown in osition in Fig. 8, the same being secured to't 1e usual cross pieces a nailed crosswise between the studding of a wall. As thus shown the device is in readiness to receive the flexible tubing or covering for insulated wire terminals. After these have been placed in position the wall is lathed andplastered as shown in Figs. 1 and 2, the top margin of the inclosure for the terminals being flush With the plaster. The switch after being placed in osition upon the inclosure is extremely rigi bein rectangular outline having upturned margins and provided with perforations tO-I'GCQIVG, and holding means to secure, flexible tubing, and a sheet metal inclosure of substantially cylindrical form mounted upon thebottom plate, the inclosure being open at the front and rear and provided'with integral extensions at its rear margin of substantially rectangular sha e and dimensions to fit within the u'pturne( margins of the bottom plate, inwardly extending integral lugs at the top margin of the inclosure providing fastening means for a switch, and means for securing the bottom plate and the inclosure in assembled relation upon a wall, substantially as described.

In testimony, that I claim the foregoing as ARNOLD E. DE FRANCE.
